IMPROVEMENT IN SAFETY-BOXES FOR REVOLVING SHAFTING.

Specification forming part of Letters Patent N o. 158,799, dated January19, 1875; application filled Y June 26, 1874.

To all whom it may concern Be it known that I, MARQUIS R. JoNEs, ofDarien, in the county of Walworth and State of Wisconsin, have inventednew and useful Improvements in Safety-Boxing for Revolving Shafting; andI do hereby declare the following to be a full, clear, and exactdescription thereof', which will enable others skilled in the art towhich my invention relates to make and use the same, reference being hadto the accompanying drawings, forming part of this specicatiomin which-Fignre l is a perspective view. Fig. 2 is a longitudinal section, Fig.3, end view of cylinder.

Myinvention relates to boxing of cylindrical form, to be placed arounduniversal joints in revolving shafting, the boxing being of wood ormetal, and so arranged as to be adapted to cover the joint when theshaftin g runsat angle. By having the boxing so'arranged, when anysubstance is caught by the same it will instantly stop, therebyTpreventing accident to the operator by being drawn around the shaft. InPatent N o. 105,695, issued to Ine July 26,

1870, I have specified and claimed boxing of cylindrical form, of woodor metal, in sections to accommodate any required size or length ofshaft, but these do not provide for the universal joint.

In the accompanying drawing, A represents the shaft 5 A', universal orknuckle joint; A", the boxing; B, hinges made of metal; a, link; a',staple b, pin. B' is a wood or metal cylvinder for boxing universaljoints. It can be provided upon the inside with one or more lugs, D, forthe purpose of holding the cylinder B' properly when in position.

The operation of my invention is as follows: The cylinder B' is placedaround the shaft near where it is to be secured. The boxing A" is thenplaced in position aroundthe shaft A' and secured. The cylinder B' isplaced in position so that the rim C occupies the end ofthe boxing, thelugs D fitting in V-shaped places in the boxing as shown in Fig. 2 at c.The

link d' passes through a slot in the spoke D', v

and the pin F passes through the same, which holds it in a iirmposition.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-v In combination with the boxing A", thecylinder B', rim O, arms c, link a, pin b, and lugs D, substantially asand for the purpose specified and described.

The above specification signed by me this 15th day of June, 187 4..

MARQUIS R. JONES.
